If you have ever abandoned a network storage box because its settings pages felt like a second job, the TerraMaster F4-425 Pro is built around a different promise: tell it what you want in plain language and let the system handle the setup. It is the company's first NAS to ship with TOS 7, an operating system that puts an AI assistant at the centre of the experience.

What the TerraMaster F4-425 Pro actually does
TerraMaster says TOS 7 was in development for more than 300 days and threads AI through the whole system, from the kernel to the interface. The headline claim is that you can handle over 90% of NAS configuration through natural language, so jobs that normally mean digging through menus, like setting up storage pools, backups or file management, can be done by typing what you want.
The hardware backs that up. The F4-425 Pro runs on an Intel N350 8-core processor with 16GB of DDR5 memory, which TerraMaster positions for 8K video transcoding and larger media workflows. Storage is where it gets interesting: a 4+3 hybrid layout pairs four hard-drive bays with three M.2 NVMe SSD slots, for up to 152TB of total capacity (32TB across four drives plus 8TB across three SSDs). The M.2 drives can run as TRAID or RAID 5, so you can use them for caching, tiering, or as fast primary storage.
The AI angle, and why it matters
The more notable part is the software. TOS 7 supports one-click installation of OpenClaw, an open-source AI assistant project, which lets you control system settings, file management and backups through text. Sitting on top are automation features that run on their own: automatic photo backup and sorting, 4K media fetching, scheduled task management, and a round-the-clock security patrol that watches for unusual activity and flags it.
This fits a wider shift across consumer and small-business tech, where companies are wrapping a conversational layer over software that used to demand technical know-how. For a NAS, which has always been capable but intimidating to set up, that pitch lands more naturally than most. The people TerraMaster is aiming at, creative teams, photographers sitting on large RAW libraries, and small businesses, are exactly the ones who want the capability without the administration.
Price and Malaysian availability
At launch, TerraMaster lists the F4-425 Pro from US$799.99 for the version reviewed here, which pairs the Intel N350 with 16GB of memory, alongside a lower-cost Intel N305 model with 8GB. It is sold through Amazon and TerraMaster's own store, with a 20% launch discount running from 23 June to 6 July 2026. Malaysian pricing and local availability were not confirmed in the announcement, so buyers here are looking at importing for now, and it is worth weighing shipping and duties before ordering.
For the spec sheet: the unit handles NTFS, APFS, exFAT, EXT4 and FAT32 file systems and works with macOS, Windows and Linux.
The takeaway
The F4-425 Pro is a bet that the hardest part of owning a NAS is not the hardware, but the setup. If TOS 7 delivers on its natural-language promise, it could make serious storage a good deal less daunting for the people who need it most.
